Surveyor helps in all of the following except
1) Determination of the clasp placement
2) Determination of the guiding planes
3) Determination of the support to the RPD
4) Determination of placement of the major connector
Prosthodontics
Answer: 3
A surveyor is a device used in the fabrication of removable partial dentures (RPDs) to assess and establish the path of insertion and removal. It is primarily involved in determining the guiding planes and the placement of the major connector and retentive elements like rests and minor connectors. It does not directly assess the support provided by the underlying tissues to the RPD, which is influenced by factors such as the edentulous ridge contour and the type of RPD design.

Guiding planes are
1) Located adjacent to the edentulous area
2) Located far anterior to the edentulous area
3) Help in the stability of the denture
4) Provide a different path of insertion and removal
Prosthodontics
Answer: 1
guiding planes are flat, polished surfaces on the abutment teeth that guide the RPD along a specific path during insertion and removal. They are located adjacent to the edentulous area and are crucial for the proper seating and function of the denture.
